Reinforced concrete structures constitute the basis of our infrastructure. Their functionality and structural safety is essential to maintain our mobility and the industrial performance of our societies. Unexpected maintenance can lead to serious economic consequences. Most industrial countries are faced with the fact that the reliability of their infrastructure has decreased over the past decades due to ageing and associated durability issues. Most often reinforcement corrosion is the major problem with respect to ageing phenomena observed. Therefore, data from corrosion inspection and their implementation in probabilistic corrosion condition assessment are considered to be of major importance to assist engineers in the maintenance process. Reliable information about the corrosion condition state can be derived through half‐cell potential measurements. The half‐cell potential measurement method is an easy to apply nondestructive measurement method to detect ongoing corrosion. The procedure on how to update the service life based on a probabilistic treatment of measured half‐cell potentials is presented in a case study of a chloride‐contaminated reinforced concrete structure. Besides the chosen probabilistic model, major impact on the accuracy of the updated service life has the evaluation of the half‐cell potential measurements.

隧道结构的概率腐蚀条件评估

钢筋混凝土结构构成了我们基础设施的基础。它们的功能和结构安全对于维持我们的机动性和我们社会的工业表现至关重要。意外的维护会导致严重的经济后果。大多数工业国家都面临这样一个事实，在过去的几十年中，由于老化和相关的耐久性问题，其基础设施的可靠性已经下降。关于观察到的老化现象，最常见的问题是加强腐蚀。因此，来自腐蚀检查的数据及其在概率腐蚀条件评估中的实施被认为对协助工程师进行维护过程至关重要。关于腐蚀条件状态的可靠信息可以通过半电池电位测量得出。半电池电位测量方法是一种易于应用的非破坏性测量方法，可以检测正在进行的腐蚀。在受氯离子污染的钢筋混凝土结构的案例研究中，介绍了如何基于对测得的半电池电位的概率处理来更新使用寿命的过程。除了选择的概率模型外，对更新后使用寿命的准确性的主要影响还包括对半电池电位测量的评估。在受氯离子污染的钢筋混凝土结构的案例研究中，介绍了如何基于对测得的半电池电位的概率处理来更新使用寿命的过程。除了选择的概率模型外，对更新后使用寿命的准确性的主要影响还包括对半电池电位测量的评估。在受氯离子污染的钢筋混凝土结构的案例研究中，介绍了如何基于对测得的半电池电位的概率处理来更新使用寿命的过程。除了选择的概率模型外，对更新后使用寿命的准确性的主要影响还包括对半电池电位测量的评估。
